Solved Given the standard equation of a parabola Chegg.com

WebNov 19, 2024 · y = a (x - h)2 + k . And if the parabola opens horizontally (which can mean the open side of the U faces right or left), you'll use this equation: x = a (y - k)2 + h . Because the example parabola opens vertically, let's use the first equation. Next, substitute the parabola's vertex coordinates (h, k) into the formula you chose in Step 1. WebGiven the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2. Equivalently, you could put it in general form: x^2 + … dr timothy wilson lynchburg va

How to find the focus of a parabola given an equation - YouTube

WebExample: Find the focus for the equation y 2 =5x. Converting y2 = 5x to y2 = 4ax form, we get y2 = 4 (5/4) x, so a = 5/4, and the focus of y 2 =5x is: F = (a, 0) = (5/4, 0) The … WebAs can be seen in the diagram, the parabola has focus at (a, 0) with a > 0. Also, the directrix x = – a. Let F be the focus and l, the directrix. Also, let FM be perpendicular to the directrix and bisect FM at point O. Produce MO to X.
